The act provides for an emergency back-up ballot, the Federal Write-In Absentee Ballot (FWAB), which can be cast by voters who "have made a timely application for but have not received their regular ballot from the state or territory, subject to certain conditions."[1]

The act does not apply to non-federal elections, although some states and territories also allow citizens covered by the UOCAVA to register and vote in state and local elections as well.[3]

An executive order issued by President Reagan on June 9, 1988, designated the Secretary of Defense as the presidential designee responsible for administering the act and authorizes the Secretary of Defense to delegate the responsibilities under the act and executive order to any person or persons within the Department of Defense.[4] Department of Defense directives issued by Secretaries of Defense have delegated responsibilities for the FVAP to a FVAP director. The current director[when?] is Matt Boehmer.

The Uniformed and Overseas Citizens Absentee Voting Act allows U.S. citizens to vote from overseas, even if they have permanently left the United States. Since these citizens are no longer residents of a U.S. State but maintain their right to vote, legal scholars have therefore argued that United States Congress also has the authority to grant voting rights to residents of the District of Columbia.[5]

The Uniformed and Overseas Citizens Absentee Voting Act has also been challenged in federal court by U.S. citizens living in Puerto Rico. Plaintiffs in the case of Igartua de la Rosa v. United States claimed that the Act is unconstitutional because it allows U.S. citizens who move abroad to vote in federal elections, but not if they relocate to Puerto Rico. The challenge was dismissed by the courts.[6] However, in his dissent, Judge Juan R. Torruella argued that the United States Constitution neither denies citizens of Puerto Rico the right to vote for members of the United States House of Representatives nor imposes a limitation on the federal government's authority to extend federal voting rights to territorial residents under other constitutional powers.[7]
